Sample questions
-
1.A structural steel rod has a radius of 10 mm and a length of 1.0 m. A 100 kN (1.0 x 10^5 N) force stretches it along its length. Calculate the tensile stress on the rod. (Take pi = 3.14)
- A.3.18 x 10^6 N m^-2
- B.3.18 x 10^8 N m^-2
- C.1.00 x 10^8 N m^-2
- D.3.18 x 10^10 N m^-2
-
2.A square lead slab of side 50 cm and thickness 10 cm is subjected to a shearing force of 9.0 x 10^4 N on its narrow face (area 0.05 m2), giving a shearing stress of 1.8 x 10^6 N m-2. With shear modulus of lead 5.6 x 10^9 N m-2, the displacement of the upper edge is approximately:
- A.0.16 mm
- B.1.6 mm
- C.16 mm
- D.0.016 mm
-
3.Equal forces applied to thin steel, aluminium, brass and copper wires of the same cross-section show that 2000 N is needed for a 0.1% strain in steel versus 690 N (Al), 900 N (brass) and 1100 N (Cu). This implies:
- A.aluminium is the most elastic
- B.steel is more elastic than copper, brass and aluminium
- C.all four are equally elastic
- D.brass is more elastic than steel
-
4.In the bulk modulus relation B = -p/(delta V / V), the negative sign indicates that:
- A.bulk modulus is always negative
- B.with an increase in pressure a decrease in volume occurs
- C.volume increases with pressure
- D.the body changes shape
-
5.Consider the statement: 'The stretching of a coil (spring) is determined by its shear modulus.' This statement is:
- A.True, because stretching a coil mainly twists the wire, which is a shearing deformation.
- B.False, because stretching a coil is governed only by Young's modulus.
- C.False, because stretching a coil is governed by bulk modulus.
- D.True, because a coil undergoes pure volume change when stretched.
